ATTINY85-20SF Description

Short technical summary and product information.

The ATTINY85-20SF is an 8-bit AVR microcontroller from Microchip Technology, part of the ATtiny85 series. It features 8KB of in-system programmable Flash memory, 512B of SRAM, and 512B of EEPROM, providing ample storage for small embedded applications. The device operates at a maximum clock frequency of 20 MHz and supports a supply voltage range of 2.7V to 5.5V (non-V version).

 

This microcontroller includes a 10-bit ADC with 4 single-ended channels, two 8-bit timers (one standard and one high-speed) with PWM capability, and a Universal Serial Interface (USI) for connectivity. It also features brown-out detection, power-on reset, and a watchdog timer. With six programmable I/O lines, it is suitable for compact control applications.

 

The ATTINY85-20SF is offered in an 8-SOIC surface mount package (0.209" width, 5.30mm body width) and is rated for industrial temperature range from -40°C to 85°C. The device is RoHS3 compliant and REACH unaffected, though these compliance statuses are unverified.
